Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a packaging bag bottom shaping mechanism for a packaging machine. Background Technology

[0002] In packaging machinery, for bags that require vacuum sealing or filling followed by sealing, the bottom often twists or deforms during the packaging process due to uneven stress, tension during opening, or other factors. This deformation not only affects the aesthetics of the bag but can also cause inconvenience during subsequent packaging, stacking, and transportation. For example, during the sealing process of tea bags, the bottom sealing area may twist due to improper operation or the characteristics of the material itself, resulting in varying bottom shapes and inconsistent orientations. This not only reduces the overall visual appeal of the product but also increases the difficulty of subsequent finishing and packaging. Therefore, before sealing, the bag needs to be reshaped. Existing reshaping methods often involve using a flat plate to directly lift and shape the bottom.

[0003] However, the existing shaping process is relatively simple, resulting in the bottom of the shaped packaging bag still being twisted and uneven. The shaping effect is difficult to meet the needs of shaping the bottom of packaging bags of different sizes. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a packaging bag bottom shaping mechanism for packaging machines. The mechanism clamps the two sides of the packaging bag using a vertical baffle and a shaping clamp. The movement of the shaping clamp guides and flattens the bottom side of the packaging bag, causing the bottom edge of the packaging bag to be biased to a specific side. Through the squeezing action between the supporting horizontal plate and the extrusion plate, the bottom side of the packaging bag becomes flatter.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a packaging bag bottom shaping mechanism for a packaging machine, comprising a support frame that can be raised and lowered and is mounted on the packaging machine body, a lifting component for driving the support frame to move up and down, a shaping component movably mounted on the support frame, and a driving component for driving the shaping component to move. The driving component is mounted on the support frame. The shaping component includes a first support plate and a second support plate movably mounted on the bottom side of the packaging bag. The other end of the first support plate and the other end of the second support plate are both connected to the driving component.

[0006] A vertical baffle is provided at one end of the first supporting horizontal plate, and the vertical baffle is detachably abutted against one side of the packaging bag. A shaping clamp is provided on the second supporting horizontal plate, and the shaping clamp is detachably abutted against the other side of the packaging bag. A pressing plate is also provided on the first supporting horizontal plate, and the pressing plate and the second supporting horizontal plate are respectively pressed and disposed on the two bottom edges of the packaging bag.

[0007] A slide rail is horizontally arranged on the support frame. A slider is slidably connected to both the first and second support plates along the slide rail. The drive assembly includes a rack connected to the first support plate, a rack connected to the second support plate, a motor on the support frame, and a gear connected to the output shaft of the motor. The two sides of the gear mesh with the rack and rack respectively.

[0008] The lifting assembly includes a slide rail 2 fixedly mounted on the side of the support frame, a plurality of sliders 2 slidably connected to the slide rail 2, a rack 3 fixedly mounted on the slide rail 2, and a motor 2 fixedly mounted on the packaging machine body. The output shaft of the motor 2 is connected to a gear 2, which meshes with the rack 3. All of the sliders 2 are fixedly connected to the packaging machine body.

[0009] The upper edges of both the vertical baffle and the shaping clamp are provided with guide portions that are angled upwards.

[0010] Both motor one and motor two are geared motors.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) The packaging bag is clamped on both sides by the vertical baffle and the shaping clamp. The bottom side of the packaging bag is guided and smoothed by the movement of the shaping clamp, so that the bottom edge of the packaging bag is biased to a specific side. The bottom side of the packaging bag is made flatter by the squeezing action between the support plate and the extrusion plate.

[0013] (2) By using the vertical baffles and shaping clamps to lift and flatten the bottom of the pre-shaped packaging bag, the lines of the bottom of the packaging bag are more three-dimensional and regular, and the shaping effect of the shaping mechanism is better.

[0014] (3) The lifting and lowering of the shaping component is achieved by the meshing of gear two and rack three. The vertical baffle and shaping clamp plate clamp the packaging bag by the opposing movement of rack one and rack two driven by gear one respectively. The adjustment range of the shaping mechanism is wider and the adaptability to different packaging bags is stronger. Attached Figure Description

[0020] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] See Figures 1-4 A packaging bag bottom shaping mechanism for a packaging machine includes a support frame 1 that can be raised and lowered and is mounted on the main body of the packaging machine. It also includes a lifting component 2 for driving the support frame 1 to move up and down, a shaping component 3 that is movably mounted on the support frame 1, and a driving component 4 for driving the shaping component 3 to move. The driving component 4 is mounted on the support frame 1. The shaping component 3 includes a first support plate 31 and a second support plate 32 that are movably mounted on the bottom side of the packaging bag 6. The other end of the first support plate 31 and the other end of the second support plate 32 are both connected to the driving component 4.

[0022] A vertical baffle 311 is provided at one end of the first support plate 31. The vertical baffle 311 is detachably abutted against one side of the packaging bag 6. A shaping clamp 321 is provided on the second support plate 32. The shaping clamp 321 is detachably abutted against the other side of the packaging bag 6. A pressing plate 312 is also provided on the first support plate 31. The pressing plate 312 and the second support plate 32 are respectively pressed and set on the two bottom edges of the packaging bag 6.

[0023] A slide rail 11 is horizontally arranged on the support frame 1. A slider 12 is slidably connected to the slide rail 11 on both the support plate 31 and the support plate 32. The drive assembly 4 includes a rack 41 connected to the support plate 31, a rack 42 connected to the support plate 32, a motor 43 arranged on the support frame 1, and a gear 44 connected to the output shaft of the motor 43. The two sides of the gear 44 mesh with the rack 41 and the rack 42 respectively.

[0024] The lifting assembly 2 includes a slide rail 21 fixedly mounted on the side of the support frame 1, a plurality of sliders 22 slidably connected to the slide rail 21, a rack 3 23 fixedly mounted on the slide rail 21, and a motor 24 fixedly mounted on the packaging machine body. The output shaft of the motor 24 is connected to a gear 25, which meshes with the rack 3 23. The sliders 22 are all fixedly connected to the packaging machine body.

[0025] Both the vertical baffle 311 and the shaping clamp 321 have guide parts 5 arranged obliquely upward on their upper edges. The guide parts 5 make it easier for the packaging bag 6 to fall into the shaping component 3.

[0026] Both motor 1 (43) and motor 2 (24) are geared motors.

[0027] The specific working process of this utility model:

[0028] First, the packaging bag 6 filled with materials is clamped and fixed by the bag clamp. Motor 24 is started, and motor 24 drives rack 3 23 and slide rail 21 to move up and down along slider 22 via gear 25 until the shaping component 3 is located at the bottom of the packaging bag 6. Then, motor 43 of drive component 4 is started, and motor 43 drives slider 12 on rack 1 41 and rack 2 42 to slide in opposite directions along slide rail 11 until support plate 1 31 and support plate 2 32 respectively... First, the vertical baffle 311 and the shaping clamp 321 clamp and shape the bottom sides of the packaging bag 6. Then, under the support of the extrusion plate 312, the shaping clamp 321 guides the bottom edge of the packaging bag 6 to the space between the support horizontal plate 32 and the extrusion plate 312. Through the extrusion action between the support horizontal plate 32 and the extrusion plate 312, the bottom edge of the packaging bag 6 is guided, causing the bottom of the packaging bag 6 to be biased to a specific side, thus completing the guidance and initial shaping of the bottom of the packaging bag 6.

[0029] After guiding and initially shaping the bottom of the packaging bag 6, the reverse motor 43 is then turned to separate the vertical baffle 311 from the shaping clamp 321 and release the packaging bag 6. Then, the motor 24 is started to lower the entire shaping assembly 3 further. Then, the motor 43 is started to bring the vertical baffle 311 and the shaping clamp 321 together, lifting and flattening the initially shaped bottom of the packaging bag 6 for further shaping, thus completing the entire shaping process of the bottom of the packaging bag 6. Then, the motor 24 drives the shaping mechanism to descend and reset.

[0030] It should be noted that when shaping a packaging bag 6 with relatively high rigidity, the motor 43 can be operated multiple times to allow the shaping clamp 321 and the extrusion plate 312 of the shaping component 3 to clamp and shape the bottom of the packaging bag 6 multiple times, so as to ensure the shaping effect of the packaging bag 6.

[0031] The packaging bag 6 is clamped on both sides by the vertical baffle 311 and the shaping clamp 321. The bottom side of the packaging bag 6 is guided and smoothed by the movement of the shaping clamp 321, so that the bottom edge of the packaging bag 6 is biased to a certain side. The bottom side of the packaging bag 6 is made flatter by the squeezing action between the supporting horizontal plate 32 and the squeezing plate 312.

[0032] The bottom of the packaging bag 6 after initial shaping is lifted and flattened by the combined vertical baffle 311 and shaping clamp 321, making the bottom lines of the packaging bag 6 more three-dimensional and regular, and the shaping effect of the shaping mechanism is better.

[0033] The shaping component 3 is raised and lowered by the meshing of gear 25 and rack 33. The vertical baffle 311 and the shaping clamp 321 clamp and shape the packaging bag 6 by the opposing movement of rack 41 and rack 42 driven by gear 44 respectively. The shaping mechanism has a wider adjustment range and is more adaptable to different packaging bags 6.

[0034] The technical features of this utility model not described can be implemented by or by using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model should also be within the protection scope of this utility model.
